Product Description

Seedless - Sweet - Healthy Grapefruit

Versatile and Seedless  
The Ruby Red is America's favorite grapefruit. If you enjoy the flavor and health benefits of grapefruit, but dread the tedious work of cutting it up and removing the seeds, then you'll love this grapefruit tree.  The fruit is seedless! It's also easy to peel, to prepare and enjoy!  

Grows When Many Plants are Dormant
Peak fruiting season for the Ruby Red Grapefruit is December to May.  You'll get an abundance of sweet grapefruits during the winter months. If you're a fruit or vegetable grower, then you likely anticipate the summer months when your bounty comes to harvest. The Red Ruby Grapefruit Tree unfailingly delivers delicious fruit during the "off-months." This tree is amazingly fruitful and will reward you with a lifetime of plump, seedless citrus!

The rich green leaves of the Ruby Red Grapefruit tree are vibrant and thick. The grapefruit is a pale lemon color blushed with pink. Reaching heights of up to 20 feet (unpotted), you can even line your property with these citrus trees!  However, you can easily keep your tree pruned to the perfect height of 5-6 feet tall.  When grown as a potted patio plant, it will thrive anywhere in the country. Just bring it indoors during the cold months, and make sure you put it near a sunny window.  You'll enjoy its beauty and summer citrus fragrance all winter. 

Countless Health Benefits
Start your day with a healthy dose of vitamin C, potassium, and fiber.  Grapefruit has many health benefits - from our metabolism to our immune system.  Studies show that a group who ate a half of a grapefruit before every meal lost an average of 3 and a half pounds over 12 weeks.  The fruit boosts metabolism and is a good source of water, which helps you stay hydrated.  The high content of Vitamin C has multiple health benefits. If you suffer from allergies, this grapefruit can actually act as an antihistamine, lowering histamine levels!  It's also known to reduce the risk of certain cancers. In addition to that - it's been proven that the citrus aroma alone can have a calming effect, reduce stress and combat depression.

Various Ways to Enjoy
Enjoy the citrusy goodness of grapefruit sprinkled with brown sugar or honey. Feeling adventurous? Add a dash of cinnamon or nutmeg to the sweet, tangy flavor of the Ruby Red Grapefruit. Grapefruit adds a distinctive flavor to tuna, spinach, shrimp, chicken and chef salads. Dip slices in yogurt or toss into a salad with your favorite mixed greens. Toss a bundle into a juicer and enjoy a flavorful burst of fresh grapefruit juice.

Ruby red grapefruit

The ruby red grapefruit came with fruit on the tree. I have ordered a lot of trees from them. Highly recommend to everybody fast growing trees. Fast shipping and reliable. Thank you very much

Just Received a New Planting

I don't have any fruit photos to share yet because I just received the young planting. I've got a while to go before my plant bears fruit. With the plant I received a "Dormant Leaves" notice which is apparently typical this time of year. Wish me luck!

Great Tree and great customer service

I totally recommend buying from this company and this tree.... Someone must have stolen it when it arrived (the post office said it was delivered but it wasn't anywhere to be found) I called customer service and they quickly sent another tree. It came healthy with fruits already growing... It continues to grow and is healthy..

Somewhat disappointed

Ordered the plant in November as website indicated that it was an appropriate time to do so. I have a greenhouse so planned to place it in there. When plant arrived it was clear that it had probably sat in an unheated delivery warehouse or truck as it was showing signs that it may have frozen. Upon receipt I immediately replanted it and placed it in the greenhouse. Over the next month it dropped all leaves and was just a stick standing out of the pot. This spring I notice some new buds down below on the stalk (the upper part of the stock was dead). As of this writing the buds have sprouted and are about 1 inch long. I suspect I won't see much this year and am hoping that it will eventually leaf out and again hopefully will bear fruit at some point. It would seem that there should be shipment restrictions to either delay deliveries to colder climates to a more appropriate time of the year or ensure that the plants are shipped in a warm enough environment so that they don't freeze.

Healthy and strong

The tree is gorgeous - hopefully we will see fruit this year! My one year old loves grapefruit so we're excited to grow our own more naturally than store bought fruit!

Planting & Care

The Ruby Red grapefruit (or Citrus paradisi “ruby red”) is a citrus tree that is known for producing a yellow fruit with a seedless, red flesh interior. Also referred to as a “redblush tree”, the Ruby Red is a fast growing tree that can get to a mature height of 15-20 feet tall (if left unpruned) and a width of 8-10 feet. The tree is a tropical citrus and will thrive well if planted outdoors in zones 8-11 but can be potted and brought indoors for zones 4-11 during the colder seasons. The best time to plant a new Ruby Red is after the threat of frosts have passed and before hot summer heat sets in.

Choosing a location: Location is very important when deciding where to plant your new grapefruit tree. These trees must have a full sun location with well draining soil. Avoid planting within 25 feet from buildings, driveways and sidewalks for adequate space to grow. Amending your soil before planting is recommended and a drainage test should be done on the soil. Dig a 1 foot by 1 foot hole, fill it with water and wait one hour. If the hole has drained all the water, then the location is good. If there is water retained, then amend in some sand and perlite.

Planting directions (in ground): Try to find a spot on the southernmost area of your home for optimum sun exposure and optimal cold weather protection.

1) Make your hole twice the size of the root ball and just as deep to accommodate the root system.
2) Keeping your tree straight, begin to back fill the hole (be sure the bud union is just above the soil surface). When you have the hole half way filled, firmly press down on the soil to rid it of any air bubbles and then add water to settle the soil.
3) Back fill until the hole is level with the surrounding soil or slightly mounded. Citrus hates to be in any standing water.
4) Apply a 3-4 inch layer of organic mulch such as leaves, pine needles, hay or compost and spread to the edge of the canopy. Keep the mulch 2-3 inches back from the trunk to discourage rot, disease and insects. Water slowly and thoroughly.

*TIP* For Hot, dry areas where sunburn can be an issue, cover the trunk of the tree. You can use an equal mixture of non-enamel, flat, latex paint (interior) mixed with water or just wrap the tree.

Planting directions (potted): Avoid using any type of porous containers as soil moisture is more difficult to monitor. Try and find a nice smooth edged pot like plastic which is also more lightweight and easier to move in or outdoors during cold/hot seasons.

1) Your pot should have multiple drainage holes for water to pass through easily. Drainage is essential!
2) Your potting soil should be a good quality mix that is lightweight and has inorganic materials such as vermiculite and perlite which will assist with drainage and aeration. Avoid any potting soil with chemical wetting agents.
3) When you go to pot the tree look for the grafting union. This is where the fruit tree was grafted to the root stock slightly above the root ball. This needs to remain above the soil line. Tamp down on the soil slightly to avoid air pockets.

Watering: Be sure to water your tree regularly for its first year once every 5-7 days and more frequently during the hot season and periods of extended drought. Water deeply right at the base of the tree so the root ball stays moist. After the first year the tree’s roots will become a bit more established and you can reduce to watering once every 7-14 days. Water further out from the trunk at this point to ensure all of the roots are receiving an ample amount of moisture.

Root rot is always the biggest concern with potted citrus trees so you will have to monitor the soil moisture closely at first to get an idea for how often watering will be needed. A good way to indicate when you need to water is by using your index finger. Stick it into the pot and feel around for moisture, if there is still some present in the soil, hold off on watering. If it feels like it is drying out on the top couple inches, water just enough until you see it escaping the drainage holes and stop. The aerated potting mix should assist with the drainage.

Pollination assistance: You can pollinate your indoor trees by hand since most people do not keep a healthy bee population within their home. Simply take a small, dry, fine tipped paint brush and stick it into the center of the bloom. Swirl it around and collect the pollen on the brush. Go to the next bloom and repeat the process until every bloom has been treated. Do this once daily and don’t wash the paintbrush until after the blooms have been pollinated. The bloom will fall of naturally and the fruit will begin to form.

Pruning: As with most citrus trees, suckers can form near the base of the tree and rob the primary trunk of nutrients if left unchecked. Remove these growths as they appear by pinching them off of the tree or use a sterilized pair of cutters to remove them. You can easily sterilize your tool(s) by wiping them with a household rubbing alcohol. Prune off any dead or damaged branches in the early spring after the threat of frosts has passed. DO NOT prune your tree more than absolutely necessary to avoid the spread of “gummosis.”  This can be a major health threatening issue that comes from excessive pruning of the grapefruit tree. The potted Ruby Red will not require any pruning, it should develop its natural shape on its own.

Fertilizing: During the spring and summer months, feed your Ruby Red with a tablespoon of ammonium sulfate once a month during the first full growing season. The following year use a ½ cup of the sulfate once every 4-6 weeks beginning in February and ending in August. The third year use 1 ½ cups of the sulfate in the same time frame (Feb-Aug). Water thoroughly after each feeding.

Container grown Ruby Red grapefruit trees will require a well balanced fertilizer formula specialized for growing citrus. This formula already contains all of the micronutrients that the tree will need. Feed the trees regularly, but be sure to follow the directions on the fertilizer’s packaging to ensure you don’t overdo it. The typical time frame for container grown citrus is to start in February, and provide fertilizer once every 4-6 weeks until September.
